Antivirus Kills Crypto Locker
This brief video shows Cylance Antivirus handling a Crypto Locker Attack. The Java Script File was enclosed in a ZIP file, so I saved it to this computer. I have the Cylance Protect window and the Task Manager open on this system when I double click on the Java Script File. This Java Script File is heavily obfuscated, but it downloads a known Crypto Locker virus called "Lockey" and then begins encrypting the user's files. Cylance PROTECT antivirus kept the downloaded file from running and quarantines the file.

SentinelOne Detects KeyPass Ransomware
KeyPass is a new ransomware threat that has hit at least 20 countries since August 7th and appears to be spreading still further by means of fake software installers. The victim's data is encrypted with a ".KEYPASS" extension and ransom notes are deposited in each directory that is successfully encrypted. The ransom note demands $300 and attempts to reassure the victim by offering to send proof of decryption ability in advance of payment. The victim is encouraged to send the attacker a sample of a small encrypted file. After doing so, according to the note, the victim will receive an unencrypted version of the file for free. Clearly, the attackers are adopting the same level of concern for 'user experience' as legitimate software developers in order to maximise their profits.

This video shows how to spot an email containing Cryptolocker. The email has a Microsoft Word attachment and claims to have been scanned by "Symantec Email.cloud service." Opening the Word attachment doesn't cause the virus to activate because the Word macro settings are set to prompt user to enable the content. Only when the Word content is enabled does the virus activate and encrypt the files on the computer. Jake Nonnemaker CEO - AXICOM, Inc.

How to prevent the CryptoLocker Virus
How to Prevent the CryptoLocker Virus CryptoLocker is a new family of ransomware whose business model is based on extorting money from users. This continues the trend started by another infamous piece of malware which also extorts its victims, the so-called ‘Police Virus’, which asks users to pay a ‘fine’ to unlock their computers. However, unlike the Police Virus, CryptoLocker hijacks users’ documents and asks them to pay a ransom (with a time limit to send the payment). When Data-Tech customer was hit with the dreaded “Cryptolocker” virus, Data-Tech sprung into action and restored the network with astoundingly little downtime. On June 15, 2015, Data-Tech customer was affected by a new strain of the Cryptolocker virus. Cryptolocker is a Ransomware Trojan hidden in executable programs that appear to be benign, typically found in emails falsely claiming to be from popular brands such as UPS or Amazon. Once an unsuspecting user clicks on the executable, the program starts running in the background, encrypting all local Word, PDF, Excel and other popular files. Once the local encryption is complete, the virus moves to the shared drives attached to the device and begins to encrypt the files therein. There's a huge threat roaming around on the Internet right now: A nasty piece of ransomware called Cryptolocker. Many organizations are being infected with this malware, but fortunately, there are surefire ways to avoid it and also ways to mitigate the damage without letting the hackers win.

How to remove CryptoWall 3.0 virus (New version CryptoWall removal guide)
CryptoWall3.0 removal guide. CryptoWall 3.0 (new version CryptoWall) is one of many ransomware trojans that encrypt the personal files on your computer and demand a bitcoin payment before you can restore them. Victims of the ransomware are given 168 hours (7 days) to pay $500 in Bitcoins if they want to recover their files. After the 7-day deadline, the amount increases to $1,000. The CryptoWall3.0 malware, distributed via spam and malvertising campaigns, helped cybercriminals make a lot of money. What is CryptoWall? CryptoWall is a file-encrypting ransomware program that was released around the end of April 2014 that targets all versions of Windows including Windows XP, Windows Vista, Windows 7, and Windows 8. In 2015, the malware developers released a new version of CryptoWall called CryptoWall 3.0, there aren’t any major differences between CryptoWall 3.0 and the previous variant. CryptoWall 3.0 will also create 3 files:HELP_DECRYPT.PNG, HELP_DECRYPT.URL, HELP_DECRYPT.HTML, HELP_DECRYPT.TXT. If infected with CryptoWall 3.0, HELP_DECRYPT.PNG, HELP_DECRYPT.URL, HELP_DECRYPT.HTML, HELP_DECRYPT.TXT files in each folder that files were encrypted and in the Windows desktop. The HELP_DECRYPT.TXT file contain information: What does this mean ?

Using visual aids and humor, Skoudis breaks down the best practices for protecting your organization against new and ever-changing network vulnerabilities. He walks through the specific steps to take when under ransomware attack -- and what decisions to make in advance of any attack including deciding who decides. Fellow panelist, Michael Assante, Director of SANS ICS Training Programs, discusses the larger, broader reaching IoT devices: industrial IoT that controls critical national infrastructure. When those facilities are attacked by ransomware and crypto ransomware, hundreds of thousands of people are potentially impacted. Assante raises the question of: What should we automate, and what should we hold back on?

Turning Trickbot: decoding an encrypted command-and-control channel
This presentation by Andrew Brandt (Symantec) was presented at VB2017 in Madrid, Spain. Trickbot, which appeared this year, seems to be a new, more modular, and more extensible malware descendant of the notorious Dyre botnet trojan. Like Dyre, Trickbot communicates with its command-and-control network over TLS-encrypted channels, which it uses both to exfiltrate an enormously detailed profile of the infected machine and any stolen data, as well as to receive payloads and instructions. This session will comprise a walkthrough of a typical Trickbot infection process, and its aftermath, as seen through the lens of a tool used to perform man-in-the-middle decryption. To collect this information, I infected a number of both virtual and bare-metal devices with Trickbot and then permitted the infected machines to beacon for anywhere from a few hours to a few weeks, all the while MITM-ing the traffic and recording it on a retrospective analysis tool. Finally, we will report our observations about the general behavioural rules that Dyre follows, and offer practical advice to incident responders or malware analysts who might need to identify a Trickbot infection, or deal with the consequences of its aftermath. https://www.virusbulletin.com/conference/vb2017/abstracts/last-minute-paper-turning-trickbot-decoding-encrypted-command-and-control-channel

One-Click Fileless Infection
This paper was presented by Himanshu Anand and Chastine Menrige (Symantec) at VB2016 in Denver, CO, USA. In the last year, there has been growing interest in a technique known as fileless infection, where malware authors compromise computers without writing any files to disk. This technique allows the threat to evade detection from file-scanning software while still remaining persistent. This paper will explain the different fileless infection methods, as well as a new tactic which can allow attackers to perform fileless infection using a classic one-click fraud attack and non-PE files. Traditional malware is contained in a file on disk. A registry run key links to this file in order to make the threat persistent. With a fileless infection, the malware does not exist on the compromised computer as a normal file. Instead, it is located in a subkey within the computer's registry as a script, such as Windows PowerShell, VBScript, or JavaScript. The payload in the registry is called every time Windows starts. The one-click fileless infection technique we've seen uses JavaScript, though different scripts could also work. The infection arrives on the computer through an .hta file, which places the JavaScript payload into a registry subkey. The JavaScript code can be triggered every time Windows starts by calling: rundll32.exe javascript:"\..\mshtml,RunHTMLApplication ";alert('payload'); The JavaScript code can read and decode encoded data from another subkey. This data injects the payload into memory. Every few minutes, the payload checks for its registry entry. If the entry has been deleted, then the payload recreates it so that the infection remains persistent. The first widespread threat we saw using the fileless infection technique was Trojan.Poweliks in 2014. Many other trojans followed suit as they evolved: Trojan.Bedep and Trojan.Kovter adopted the same technique after Poweliks. Based on our research, the most common infection vectors for this technique include the following: Drive-by downloads / Exploit kits: In August 2014, the Angler EK became the first kit to infect a computer without writing the malware on the disk. Instead, the malware was injected directly into the process running the exploit plug-in. Over time, we have seen more instances of fileless infections using this infection vector. Downloaders: Through this method, the downloader is written onto disk. Once it gets executed, it will retrieve the final payload and may delete itself. The final payload remains in memory, acting as the fileless infection. One-click fraud: One-click fraud, which mostly targets Japanese and Chinese users, tricks a user into clicking a tempting offer. If this works, then a malicious file is downloaded onto the computer without the user's knowledge. The threat displays annoying/obscene pop-ups and asks the user to pay to remove them, in a similar manner to ransomware. A variant of Kovter, which is known for click-fraud, included fileless infection capabilities. While we haven't seen many threats conducting one-click fraud in a fileless manner, sooner or later attackers may engage in this method, as it is PE-free, exploit-free, and harder to detect. This is something that our paper will explore. Our paper will explain and compare the most common ways in which malware authors use fileless infections today. We will discuss areas where we expect these methods to be used soon.

HELP DESK with Joe 38: Cryptolocker Malware
This week Zach and Joe discuss the new ransomware malware that is attacking systems called Cryptolocker. Cryptolocker is a type of malware that once it has infected teh system it will scan the entire hard drive and will encrypt certain file types most likely the ones people find important to them. For example it will encrypt pictures, word documents, spreadhseets, pictures, databse files just to name a few. Once the malware has infected the system and encrypted the files the malware demands that you pay the hackers to get your files decrypted or your files are lost forever. This virus IS NOT a hoax and the threats are REAL. Unless you have a good backup of your files you have lost everything with no chance of recovery unless you pay the hackers.

2,000 Singapore users affected by GOZ, CryptoLocker malware - 11Jun2014
SINGAPORE: The Infocomm Development Authority of Singapore (IDA) confirmed on Wednesday (June 11) that there are 2,000 users in Singapore affected by the Gameover Zeus (GOZ) and CryptoLocker malware, which have hit users internationally. A multi-national agency effort had earlier this month disrupted the GOZ botnet as well as the CryptoLocker malicious software. The IDA spokesperson told Channel NewsAsia: "The United States authorities found 2,000 affected users in Singapore and informed SingCERT (Singapore Computer Emergency Response Team), who is working with the local ISPs (Internet service providers) to notify them." "So far, no Government e-services have been affected. We will continue to strengthen all Government websites and e-services by taking the necessary security measures such as checking and fixing vulnerabilities and patching software," the spokesperson added. GOZ and CryptoLocker malware encrypt a user's information and demand a ransom from the user in order to decrypt the files. Systems infected by either of the malware could be used to send spam, participate in distributed denial-of-service (DDoS) attacks or cause users to lose sensitive information such as user names, passwords and banking data. In a blogpost on Wednesday, SingCERT identified the following systems to be affected by the two malware: - Microsoft Windows 95, 98, Me, 2000, XP, Vista, 7, and 8 - Microsoft Server 2003, Server 2008, Server 2008 R2, and Server 2012 SingCERT advised affected users to scan their computers with an updated anti-malware solution to remove Zeus and other known malware, change all user names and passwords, and to back up important files regularly. INTERNATIONAL IMPACT The United Kingdom's National Crime Agency (NCA) had issued a warning on June 2 that the GOZ botnet could be up in just two weeks, and urged people to protect their computers from an expected "powerful computer attack". The US Computer Emergency Readiness Team (US-CERT) posted a technical alert on its website the same day, announcing a multi-national effort that disrupted the GOZ botnet - a global network of infected victim computers used by cybercriminals to steal millions of dollars from businesses and consumers. "Gameover Zeus' decentralised, peer-to-peer structure differentiates it from earlier Zeus variants. Security researchers estimate that between 500,000 and 1 million computers worldwide are infected with GOZ. The FBI estimates that GOZ is responsible for more than US$100 million in losses," the United States Department of Justice stated in a separate press release. www.channelnewsasia.com/news/singapore/2-000-singapore-users/1145704.html
